I'd like to have some emergency cleanup code execute just before my app crashes. I tried using onDestroy(),, onFinal() and finalize() to no avail. Is this possible in an Android Activity?

My app keeps force closing before it starts, eclipse returns no errors in my code and my xml is good.
package com.mhe.test.scan;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class main extends Activity {
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button myScanButton = (Button) findViewById(R.id.myScanButton); myScanButton.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
startActivityForResult(intent, 0);
} } );
} EditText totalbox = (EditText) findViewById(R.id.totalbox);
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) { if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
// Handle successful scan totalbox.setText(contents)
} else if (resultCode == RESULT_CANCELED) {
// Handle cancel totalbox.setText("@string/bummer");
} } } }
Essentially it is supposed to call zxing Barcode Scanner to scan a barcode on a button click and return the result into an EditText field.
Is there any way for an activity to register for being notified if a wait/force close dialog is shown or alternatively if the user selects force close, a way to detect that in ondestroy()?
View 6 Replies View RelatedSo I read through the SDK docs and I thought that calling a new activity(browser) as part of a task (myTask) will mean that activity* (browser) will close when a user closes the task (myTask) But I am left with a browser window.
Here is my scenario (in sudo code);
CODE:..........
Question 1: What is the cleanest way to ensure that when a user closes my app, any outside activities called will be closed to.
Question 2: Does a callback URl start a new Task, or use one in the stack if available?
Is there a way to notify an activity/service of a force-close request right before it gets killed?
I mean when the user hits the force close button in Menu>Settings>Applications>Manage applications>app name>Force Close.
When I start my (soon-to-be) android game (from eclipse) it opens, but immediately force-closes.

The interesting line here is (I think):
07-09 17:12:35.719: ERROR/AndroidRuntime(3866): Caused by: java.lang.ClassNotFoundException: org.anselm.eickhoff.rhythm.RhythmGameActivity in loader dalvik.system.PathClassLoader@4001e740
Which surprises me, because I have this class (in the right package)
Edit: to clarify, added the first line which I had omitted (together with the imports)
package org.anselm.eickhoff.rhythm;
...
public class RhythmGameActivity extends Activity {
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
} @Override public void onPause() {
} }
and that's all it does!
I also registered it in the manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.anselm.eickhoff.rhythm"

Our application will expose a Service that can be called by Activities in other people's applications.In many cases, the parent applications calling Activity may be paused before our Service completes. I am looking for the best way for a Service to communicate back to the calling Activity that may have been paused.These are the known options:
(1) Require calling Activities to have a registerReceiver() with a custom action and broadcast to that from our Service. The only way to secure this registerReceiver() is with a signature-based permission.As our Service communicates with any number of unknown 3rd party apps,we can't sign our Service's parent app with all these unknown certificates. These apps would therefore be exposing an unsecured registerReceiver() on their Activity. Would ideally like to avoid requiring this.
(2) Create a PendingIntent to send results back to the activity and give it to our Service. Our Service would send data to calling Activity's onActivityResult(). Each time the result is delivered, the calling Activity will go through onPause() and onResume() but this should be OK.
(3) The calling Activities could create a Handler. The Activity would then create a Messenger pointing to that Handler and send it to our service. Our Service can then use the Messenger to deliver our message back to the calling Activity.
My activity calls a browser activity where the users submits their info to retrieve a PIN. That PIN is then sent as a parameter to a url specified in the request.
View 4 Replies View RelatedI have an activity class(Application Class ) which calls a service class(Service Class) and closes. The service class takes about 5 seconds to complete its task and calls a method which is present in another class(Callback Class). Now according to the result, the callback needs to notify the Application class.Once i get the callback from the service, I tried calling a method defined in the Application class. In this method i create a new intent of Application class and call startActivity(Application Class). But this is not working. Can anyone tell where i am going wrong and what can I do to solve this issue.
View 5 Replies View RelatedI want to find the dimensions of the various views in my layout. My understanding is this can only be done after layout is completed since layout is somewhat dynamic. So, after the activity calls setContentView() and then returns control on the main thread to the OS so that layout can occur, how do I get a notification that layout has completed so I that I can query the views for their dimensions? On a related topic, can I find out the status bar's height or least the screen's full size (from which the status bar's height can be calculate by subtracting my window's height)?
View 2 Replies View RelatedIn my application, there is a service which has a running thread to capture data from remote server, and also this service is triggered by AlarmManager, for example let 1:00 am to start the service. After the service finish the task, it stop itself and the main activity need to update GUI. I don't know how to let the main activity know when the the service stopped, so that the main thread can update GUI.

View 2 Replies View RelatedI've noticed that whenever I introduce some new awful bug to my app and it crashes, Android just keeps starting it up over and over again. I eventually have to hit the dial button on the phone just to make my app lose focus. I searched this group's posts and the developer documents.I can't find anything about this. Is this usual behavior? If so, is there some way to disable it? Maybe it's just my coming from a desktop background, but I kind of think that when something is closed, it should stay closed, especially if the reason it was closed was that it crashed. And of course, I hope my final app never force closes, but with all the different hardware you never know.
View 6 Replies View RelatedIs there an app that lets you set a countdown timer on another app which causes it to force close. For example, I use my Eris as my MP3 player and would like to listen to it while I go to sleep, however I don't wanna let it play all night while I'm sleeping maybe just an hour or so.*Edit* Nevermind I found an app that does the job. Its called Music Sleep. It lets you set a timer that will close your music app in case anyone else was interested. It only costs 99 cents
